WG welcomes Hugo Haas from Yahoo! as an observer

discussion of interop event

yves: having people in a room would help socialisation and crafting of tests

jonc: getting end users involved would be a challenge

pauld: getting vendors to participate has been difficult
... organising around the W3C Workshop on Enterprise Services might help

hugo: an interop event sounds appealing, not too high cost from vendors and may help build test cases

yves: also a mini-TP around then in Boston, could be co-located

pauld: OK, let's consider an event early 2007 in Boston, we can always cancell if we get no interest

Status of Deliverables

pauld: built some "traffic lights" to schema validate our instance documents, and if the detected patterns match the expected status:

http://www.w3.org/2002/ws/databinding/patterns/6/09/

pauld: can we change the normative XPaths without the change being considered substantive?

yves: we will at least have the text?

pauld: we have very little text as the XPaths are normative

yves: sounds like we would have to go back to Last Call

pauld: will ensure the XPaths are correct, then!

pauld: will call for a vote to go to Last Call for Basic on Tuesday

pauld: can we publish a first WD of Advanced?

vlad: sections 2.1 and 2.2 are missing

pauld: OK, that looks editorial, I'll fix./

pauld: hearing no objections, we'll plan to publish first WD of Advanced alongside LC of Basic

ISSUE-2: test suite

pauld: worked on the test client, still Perl, still works on separate files

hugo: took a brief look, seems sensible approach

otu: took a look at WCF, svcgen no longer generates a server databinding, only interfaces. Suggested we use Visual Studio 2005, but you want a scripted interface.

otu: also started to look at Python ZSI, struggling with lack of documentation

pauld: WCF still generates a client databinding no?

otu: we can turn this inside out

yves: may get time to work on XMLUnit later this week

pauld: will publish test suite page and ping WSO2 for assistance

ISSUE-12: identifying a conformant schema

pauld: there's a stylesheet on the bottom of the patterns page, should work on Schemas and WSDLs (though not tried many WSDLs)

pauld: we still need to follow schema import and include and detect UTF-8 etc

yves: if we think the pattern detector we have works, but will still look at an alternative approach

pauld: could still be useful, but let's make it lower priority than XMLUnit

pauld: anticipate having to write some non-XSLT code to check some of our non-XPath based assertions

ISSUE-68: xs:import of Schema 1.0 namespace

pauld: submitted evidence on why it's not Basic pattern, but is it Advanced?

vladislav: SAP implementations now support this

pauld: so it sounds advanced, let's see if Priscilla comes up with any new info on why it might be a bad idea before closing it.

ISSUE-10: Mapping Element and Type names

vladislav: we have had limitations mapping Unicode characters to language constructs
... also we have length limitations

hugo: do you have a sense of a "safe" character set?

<Yves> http://www.w3.org/2002/ws/databinding/issues/10/

pauld: difficult - Fortran or COBOL might offer a lowest common denominator, but no obvious lowest subset exists, but we seem to be moving towards Python's subset
... plan to close this issue based on testing next week
